Question:

Is it proper to fly the flag of the United States at night?

Answer:

The Flag Code states that it is the universal custom to display the flag only from sunrise to sunset on buildings and on stationary flag staffs in the open. However, when a patriotic effect is desired, the flag may be displayed twenty-four hours a day if properly illuminated during the hours of darkness.
